Chasing high chromium for the last three ICP Triton Tests. Just purchased and received a hanna chromium LR checker to test all water sources. Found the RODI water using aquatic life 4 stage shows steady readings at 12 ppb. Tested a freshly mixed salt and read 12 ppb. Tested the RODI with a TDS and reads 0. The cartridges were changed out around Christmas.
Is it possible the RODI unit isn't removing chromium? Should I add additional cartridges for carbon?
